ABSTRACT

OBJECTIVE:

The purpose of this study was to determine whether familial non-medullary thyroid cancer (FNMTC) is more aggressive than sporadic thyroid cancer. SUBJECTS AND

METHODS:

We compared the clinical behavior and outcome of 16 subjects with FNMTC from 7 unrelated kindred with those observed in 160 subjects with sporadic PTC (SPTC) from our database.

RESULTS:

The only different baseline characteristics observed between both groups were bilateral malignancy, 38 percent vs. 24 percent, respectively (p = 0.03), and lymph node metastasis, 56.2 percent vs. 39 percent, respectively (p = 0.01). Considering the outcome, in the FNMTC, 9 (56.2 percent) patients were rendered free of disease, one patient died from thyroid cancer (6 percent), and 6/16 (37.5 percent) had persistent disease. In the SPTC Group, 87 (54 percent) patients were considered free of disease, 11 (7 percent) died due to PTC, and 62 (38 percent) had persistent disease (p = ns).

CONCLUSIONS:

Despite the higher incidence of lymph node metastasis in FNMTC patients this situation seemed not to alter the compared outcome.
RESUMO

OBJETIVO:

O objetivo deste estudo foi determinar se o câncer de tiroide não medular (CNMF) é mais agressivo do que o câncer esporádico de tiroide. SUJEITOS E

MÉTODOS:

Comparamos o comportamento clínico e a evolução de 16 portadores de CNMF de sete famílias não relacionadas com 160 CP (câncer papilífero) esporádicos de nosso serviço.

RESULTADOS:

As únicas diferenças nas características basais dos grupos eram malignidade bilateral 38 por cento vs. 24 por cento, respectivamente (p = 0,03), e metástases linfonodais, 57,1 por cento vs. 39 por cento, respectivamente (p = 0,01). Em relação à evolução, 9 (56,2 por cento) pacientes com CNMF ficaram livres de doença, um paciente faleceu devido ao CP (6 por cento) e 6/16 (37,5 por cento) apresentavam persistência da doença. No grupo de CP esporádicos, 87 (54 por cento) foram considerados livres de doença, 11 (7 por cento) morreram em decorrência do CP e 62 (38 por cento) apresentavam persistência da doença (p = ns).

CONCLUSÃO:

Apesar da elevada incidência de metástases linfonodais nos pacientes com CNMF, essa situação não parece alterar a evolução dos dois grupos em longo prazo.
